According to the present invention, a planter of conventional form is provided and the novel pit plowing attachment is carried at the rear thereof. The pit plowing attachment comprises'a pair of stub shafts, one mounted at the rear of each covering wheel of the planter and carrying semicircular disks for forming the pits off the line of the planting.

Numeral H1 represents a planter of well known form, such as shown in the patent to- Ford, No. 1,443,173 of January 23, 1923. There is a first frame l l which is supported by means of a shaft l2 on which, at its outer ends, covering wheels 13 are journaled. A cross member M extends between the sides of the U-shaped frame. There are seed can [6 carried at the forward end of 5 .seedbQQ sandru n r ll -u Ex en i etwee h i ansathe i a sh f 11 d v by a smackcha '3 d eciab eozanyione Qf thre gears 1205121; nd. 1% 9 th h t; 1-

Se ured a theerear'of. the first. frame member I! are bracket members 34' 5130Whi0h is pivotally, attached asecond frame which consists of a pair of rearwardly: extending members .35, to which a cross' member 36;is,fixed or welded. A pair; of L -shaped members. 3 l; is adjustably pivot- @(l gl'lQQdfithegi-Bflds of the'cross member 36 and has depending; arm a carrying shafts 33 rotatably mounted -in;;.- bearing sleeves; 38% At each end of the shafts 38 there is a pit forming element-.1 39 of approximately semicircular shape. The inner ends of the horizontal arms of the L-shaped members 37 are slotted, as at 42, and receive therein a bolt 43. Adjustment of the L-shaped members is had by movement of their inner slotted ends longitudinally of the planter. A nut 44 on the bolt 43 is effective to hold the L-shaped members in any desired position. In this way regulation of the angle of the pit forming elements 39 is effected, the shafts 38, which carry them, being held in line with the L-shaped members 21. Provision of a plurality of bolt openings in the ends of the cross member 36 permits lateral adjustment of members 31.

Attached to the upper side of the cross member 36 there is a bracket member 45, to which is pivotally connected a pair of links 46. Pivoted to the upper end of the links 45 there is a pair of members forming a lever 47, to one end of which is attached a handle member 48 and to the other end of which is connected a depending member 49 attached beneath the operators seat 39. This last mentioned mechanism is effective to raise the pit plowing attachment from operating position to transport position. When this is desired, the handle 48 is moved upwardly and the lever 41 pivots about its point of attachment to the member 49. 'Ihus,by virtue of the links 46, the pit plowing attachment is also raised and swung to an inoperative transport position, as indicated by dotted lines on Figure 2.

The pit forming elements mounted on each shaft 38 are shown as being 180 degrees out of phase with one another. The result is then that a pit on one side of the line of planting will be staggered with respect to the pit on the other side of the line of planting.

In operation the planter and pit forming attachment are moved along the ground, the seeds are dropped at regular intervals through the seed boots I! into the furrow formed by the runner N and the wheels 13 cover up the seeds. The elements 39 then form pits on either side of the lines along which seed has been dropped. The result is two lines of planting with two lines of pits on both sides of each line of planting.

As previously stated, the angle of the pit forming elements can be regulated by an adjustment of the inner ends of the L-shaped members 31; the slots 42 allow this adjustment. The angle of the pit forming elements will determine the type of pit formed. If the L-shaped members 31 have a considerable angle with respect to the cross member 36, then the pits formed are of substantial size. If, however, the L-shaped members 31 are moved more nearly into alinement with the cross member 36, then the pits become smaller.

It will be apparent from the foregoing description that a novel pit forming attachment for planters has been provided, as well as a novel method of forming pits and of planting. The pit forming attachment is simple in construction and can be readily attached to planters of well known types. The intention is to limit the invention only to the terms of the appended claims.

What is claimed is:

1. A corn planter including a frame, means thereon for depositing corn, means for covering the corn carried rearwardly of the depositing means in alinement therewith, and basin-forming means carried rearwardly of the covering means and on both sides of and closely adjacent the line of the covering means and the depositing means,

2. A corn planter having a frame, a seed boot and runner mounted thereon, a covering wheel mounted on the frame rearwardly of the seed boot in alinement therewith, a shaft carried rearwardly of the covering wheel, and basin-forming elements mounted on the shaft and positioned on both sides of and closely adjacent the line of the covering wheel and the runner,

3. A corn planter having a frame, a pair of seed boots and runners mounted thereon, a pair of covering wheels rearwardly of the runners and in alinement therewith, a basin-forming device carried by the planter frame and including a pair of shafts carried rearwardly of the coverin wheels, and pairs of basin-forming elements respectively mounted on the shafts, each pair straddling the line of the respective runner and covering wheel.

4. A planter comprising a first frame, runners and covering wheels in alinement on the first frame, a second frame movably connected to the first frame, means for adjusting the second frame with respect to the first frame, a plurality of basin-forming means mounted on the second frame at the sides of each of the alined runners and covering wheels, and means for adjusting the basin-forming means to affect the size of the basins.

5. A planter comprising a first frame, runners and covering wheels in alinement on the first frame, a second frame movably connected to the first frame, means for adjusting the second frame with respect to the first frame, L-shaped members adjustably secured on the second frame, and basin-forming means mounted on the L-shaped members on both sides of the alined runners and covering wheels.

6. A planter comprising a first frame, runners and covering wheels in alinement on the first frame, a second frame movably connected to the first frame, means for adjusting the second frame with respect to the first frame, a plurality of basin-forming means mounted on the second frame at the sides of each of the alined runners and covering wheels, said basin-forming means contacting the ground on the lowering of the second frame and forming basins on both sides of the alined runners and covering wheels as the planter moves over the ground.
